A stream of water molecules , held together by hydrogen bonding, forms a left‐handed helix within the helical channels of a left‐handed staircaselike metal coordination polymer. The result is a novel helix‐in‐a‐helix structure. The water‐filled channel can be seen on viewing the coordination polymer along the b axis (see picture; C gray, N blue, Ni green, O red).
